MECHANICAL MOVEMENT.

Application iled April 2, 1923. Serial No. 629,348'.

chanical Movement, of which the following` is a specification.. i K 4My invention relates to a mechanical movement, and has for its particular object the provision of a novel and improved mech- `anism adapted to be used in connection with power engines. f Y

'One object of the present invention is to provide a mechanism of this character in Awhich an engine will be absolutely prevented from stopping on dead center. c V

A further object of the invention is to provide mechanism of this character which will generally add to the efficiency of an engine when used therewith. Y

With these general objects in view and such others as will be apparent from thedescription, the invention resides inthe novel construction, combination, and arrangement and illustrated in the accompanying drawings, in which- Figure 1 is Yan elevation of an engine Vequipped with the invention; I I Figure 2, a top plan View thereof;

Figure 3, a vertical elevation, partly inv section, of the upper end of the main shaft; L, #Figure 4, a vertical section on the line 4-4 of Figure 1; and f Figure 5, a horizontal section takenVV adapted to engage overV the extreme upper through Figure 4:

The invention is shown as applied to an engine l having the usual piston 2 and fly wheel 3, which is mounted on a suitable ele-- .vated platform 4. Below the platform 4, and spaced appreciably therefrom, are arranged two horizontal parallel platforms 5 and 6, in the lowermost of which a shaft 7 is journaled in the socket bearing 8 at its lower end and through a slide bearing 9 at its upper end, the shaft being disposed vertically between the two platforms. The shaft 7 carries a pulley 10 over which a belt 11 is arranged in connection with the ily wheel .ranged in the platform 4. At a 12 disposed onthepower take-oshaftzl, whichmay be suitably mounted at any desired point.

At the upper end of the shaft 7 is disposed the universal joint 14 connected with ayertically arrangedrshaft 15 extending upwardly through the horizontal slot 16 arpoint adj acent the bottom of the platform 4, shaft 15 ,is equipped with a weight 17 carried on the Louter end of the bracket arms .18 connected at their inner ends with the shaft. by any suitable manner of fastening so thatV the weight is rigidly secured to the shaft. The

lowermost bracket arm 18 extends at right angles to the shaft whereby,'when thcshaft is in the vertical position, as villustrated in Figure 1, the weightl? will Abe in its highest -position and any displacement ,of the shaft 15 from `the vertical position will Qcause the weightto `travel'fin a downward path. .l ,j .i Y

` The upper end of thev shaft 15 is'adapted toreciprocatefin the slot 16, and' is mountedtherein in substantially semigcircular slide bearings 19 disposed in similarly formed grooves arranged in a guideway 20 mounted on the platform 4, or formed 4integrally therewith. Journaled on stub-shafts 21 received in the bearings 19, is a block 22 jhaving a central bore through which" the shaft -15 extends.' The block 22 is provided with a 'race-.way 23 in which ball bearings 24 are disposed to provide a bearing for rotation of the shaft within the block. A lever 25, provided at one end with a socket end of the shaft 15, is rigidly securedto the shaft at this point by vmeans of a set screw or other suitable fastening element 26 passed through a wall of the socket and engaged with the shaft. The lever extends laterally at a right angle from the shaftgand is. provided at lits outer' end with an integral upstanding ball 27 received in the ball bearing socket carried in the adjacent end of the lever arm 28 mounted by means of ball and socket connection on a standard 294 disposedv in longitudinal alignment with the slot 16 on the platform 4 and spaced considerably therefrom. The mounting of the lever arm 28 is such that in the vertical position of the shaft 15 the arm will assume the position in Figures 1 and 2, being arranged on a slight upward incline.

Between the guideway 2O and the lever 15, the shaft 25 is provided with a sleeve 30 rigidly secured thereto providing a bearing mounted on the collar 31 disposed thereover, which collar is pivotally connected by means of stub shafts 32 with the forked arms 33 disposed on the end of a longitudinally arranged lever 34 pivotally connected at its opposite end, as at 35, to a rocking arm 36 pivoted at its lower end. on a shaft 37 journaled in the bearings 38 disposed on the platform 4 in longitudinal alignment with the slot 16. The lever 34 is connected to the Vrocking arm 36 at a point adjacent its upper end, as illustrated in Figure 1. Between the extreme upper end of the rocking arm 3G andthe fly wheel 3 of the engine is disposed a pitman 39 whereby on rrotation of the fly wheel the arm 36 will berocked in its bearings acting through the medium of the lever 34 to reciprocate the shaft 15 in the guide 20.

By reason of the mounting of the collar v31 and the rigid connection of the lever 25 with the upper end of the shaft 15, the shaft will, when reciprocated in the slot, be rotated through the medium of the ball and socket connection of the outer end of the lever 25y with the lever 28, which lever will reciprocate in the arc of a circle, as best illustrated in Figure 2, and the rotation imparted to the shaft 15 will be transmitted through the medium of the universal joint 14 to the shaft-7 and from thence through the medium of a belt 11, over the pulley 10 and fly wheel 12 to the power take-up shaft 13. The arrangement of the weight 17 will impart an added momentum to the rotation of shaft 15, by reason of its mounting, as when the shaft is ldisplaced from its vertical position, the weight will begin to travel in a downward path and will be sufficient to carry the en- Y ginebeyond the dead center, as in normal position the weight will likewise come to rest at its lowermost point, as illustrated in Figure 1 in dotted lines.

While I have illustrated and described lcertain details entering into the construction and operation of the invention, I desire it to be understood that I do not intend to limit myself to these, but that any changes may be made in the structural details, and such modifications embodied as will fall within the scope of the invention as claimed.
